But it was originally a non-expiring link... it was terminated manually. We can't predict when it will be terminated next, so we can't possibly add a disclaimer like that. That would be like citing a release date for freeso.

These invite links have a timer the moment you create them. The wording gave the impression the timer had expiration that would have lasted for days. Of course, now that I check again those only last 24hrs or less without opting for infinite and you two confirming this was not an "expired" link changes things. Forgive the human error but I don't know what goes on over there anymore.
